MF10  
Universal Monolithic Dual  
Switched Capacitor Filter  
General Description  
The MF10 consists of 2 independent and extremely easy to  
use, general purpose CMOS active filter building blocks.  
Each block, together with an external clock and 3 to 4 resis-  
tors, can produce various 2nd order functions. Each building  
block has 3 output pins. One of the outputs can be config-  
ured to perform either an allpass, highpass or a notch func-  
tion; the remaining 2 output pins perform lowpass and band-  
pass functions. The center frequency of the lowpass and  
bandpass 2nd order functions can be either directly depen-  
dent on the clock frequency, or they can depend on both  
clock frequency and external resistor ratios. The center fre-  
quency of the notch and allpass functions is directly depen-  
dent on the clock frequency, while the highpass center fre-  
quency depends on both resistor ratio and clock. Up to 4th  
order functions can be performed by cascading the two 2nd  
order building blocks of the MF10; higher than 4th order  
functions can be obtained by cascading MF10 packages.  
Any of the classical filter configurations (such as Butter-  
worth, Bessel, Cauer and Chebyshev) can be formed.  
For pin-compatible device with improved performance refer  
to LMF100 datasheet.
